The investigation results of the size dependence of magnetoresistive effect are presented for Fe films prepared by the resistive sputtering method on a substrate heated to 400 K. Correlation of magnetoresistance with structure and phase state was deter-mined for multilayer film systems based on Fe and Cu or Cr subject to the thickness ratio of magnetic and non-magnetic layers. The thermal annealing influence on the magnetoresistance, induction of demagnetizing and saturation values was studied. The values of magnetoresistance to magnetic induction sensitivity were calculated.
